Johnybee180 FPV Quadcopter

Johnybee180 is a mini 180 size FPV racing quad which is easy to print & build and very funny to fly due to its size and agileness. You can squeeze it through every hole :)

When printed in ABS with 100% infill it's also very rigid and will survive a lot of crashes.

Frame weight is about 60 grams (ABS, 100% infill), AUW with FPV gear and 3s lipo 850 mAh is about 300 grams.

My recommended setup:
motors: 4x 1806 2280kv (or 1306 3100kv)
ESCs: 4x DYS SN16A (or similar size and amps)
flight controller: CC3D Atom (or Naze32)
propeller: 4045 (or 4045 bullnose)
battery: 3S LiPo 850-1000 mAh
FPV camera: DAL 700TVL
video TX: TS5823 200mW

Software:
BLHeli14.1 firmware for ESCs + Damped Light mode + Oneshot125
Cleanflight Luxfloat controller PIDs:
roll/pitch: 2.5, 0.040, 30
yaw: 8, 0.040, 5
looptime: 1600

With this setup you can have a greatly flying mini quadcopter for about 110 USD including FPV gear (aliexpress, banggood).

There is also a bigger version for 5" propellers (http://www.thingiverse.com/thing:1069161) and smaller for 3" propellers (http://www.thingiverse.com/thing:1091279).

Have fun!
